5. Xbox 360

Pros: Third time was a charm for Microsoft. After the fat debacle and the subsequent small band-aid, we were finally gifted with a reliable, solid, well mannered wireless workhorse.
Cons: Too bad Microsoft is limited when it comes to their R&D blood supply—when they put all their energy into the controller, they drained the life-force out of their console design. Hence the Red Ring debacle.
